Aptera, super-efficient electric-powered car

An American automotive startup company named Aptera has just launched a very promising electric car for the market. However, actually they are not a new company, the company has been established since 2005, but they went bankrupt in 2011. It was only in 2019 that Aptera was reformed by its original founders.

And now they are ready to introduce their first car to the public which is named Aptera Paradigm. The electric car is claimed to be able to go as far as 1,600 km on a single full charge. The car carries a sleek and futuristic three-wheeled vehicle design with a shape similar to a wingless aircraft fuselage, and it seems to be the reason behind its small drag coefficient, which is 0.13.

The main purpose of the Aptera electric-powered vehicle was created to eliminate carbon emissions that have been produced by conventional-fueled combustion engines. However, when the electricity itself still comes from a source that uses coal as its fuel, perhaps the idea of ​​zero emissions is still not fully realized.

The Aperta will be available in several variants that are differentiated based on the cruise capability. At the very bottom, it uses a 25 kWh battery which can last up to 402 km on a single charge. In addition there is also a 40 kWh model with a range of 644 km and a 60 kWh battery for a distance of up to 966 km.

The highest variant of the Aptera electric-powered vehicle is equipped with a large battery with a capacity of 100 kWh plus a solar panel on the roof that can absorb energy to provide an additional 64 km of mileage in the sun. The number of solar panels can be increased to be placed on the hood of the car so that there is an additional 38.8 km of mileage with solar panels alone.

Various motor drive configurations will be offered depending on the variant. No horsepower and torque figures are provided yet, but front-wheel drive models can typically hit 96 kph in 5.5 seconds. Meanwhile, this three-wheel drive car only takes 3.5 seconds to reach it. The key to the performance of this electric car is the fact that the 100 kWh battery of the Aptera electric car weighs less than 1,000 kg.

In addition, with fast charging, in one hour it can be charged to be able to go as far as 800 km. In other words, on the variant equipped with a battery with a capacity of 100 kWh, the distance is believed to be up to 1,000 miles (1,600 km) per charge. But efficiency is only part of the whole story, because Aptera Paradigm is also equipped with the ability to create its own energy.
2021 Aptera Paradigm is reportedly going to start production in 2021, and the company has received orders from the US consumers with an order fee of the US. $100. (Picture from: http://bit.ly/3nM89Hl)
The method applied is almost the same, namely by attaching solar panels to the roof of the car along with the front and rear hood. In a day (assuming the weather is not cloudy and the sun shines so brightly) Aptera Paradigm's solar panels are claimed to be able to produce electrical energy equivalent to a distance of 64 miles (± 103 km).

Of course this can mean that the Aptera Paradigm is not a fully solar powered car and still needs to be charged as usual, but at least the presence of these solar panels can help eliminate the worry that the car's energy will not be enough to reach the destination, or better known as cool "range anxiety".
Aptera Paradigm is reportedly going to start production in 2021, and from now on, Aptera has received orders from consumers in the United States with an order fee of the US. $100 or Rp.1.4 million which is refundable if the purchase is canceled. The official price tag is in the range of $25,900 (or around Rp.365 million) - $46,900 (or Rp.648 million). Of course, the cheapest price is not for a capacity of 1,000 kWh, but for 250 kWh. *** [EKA | FROM VARIOUS SOURCES | APTERA.US | FORBES.COM | GREENMATTER.COM ]

The story of one of the most iconic cars ever, Shelby Cobra

The Shelby Cobra is one of the world's iconic cars that are familiar to the automotive enthusiasts all over the world. These beautiful, powerful cars is the design of a former racing driver and legendary American automotive designer named Carroll Shelby by using the engine supplies from the Ford Motor Company, and was first introduced in 1962.
1962 Shelby 260 Cobra 'CSX2000' uses a 159-cubic-inch (2.6 L) Ford Zephyr inline 6 engine. (Picture from: http://bit.ly/3oGSXML)
His work is quite classy in the world of racing with his success in winning the Le Mans 24-Hours endurance race in France, by beating Ferrari, who was so dominant at that time. With consecutive victories from 1966 to 1969 with the legendary Ford GT40.

The Shelby Cobra is could be said as a British-American sports car uses a Ford V8 engine, is produced only briefly in Britain and the US since 1962. Well, this car is also known as the AC Cobra because it was originally made at a British manufacturer called AC Cars, which was later sold in the United States as Shelby Cobra.

The Early Models
Like most British manufacturers at the time, AC Cars used the straight-6 engine from Bristol (known as a pre-war designed engine by BMW) for its small production including the AC Ace (a two-seater roadster). This car has a handmade body with a steel tube frame, and aluminum body panels made using the English wheel engine. Until 1961, Bristol decided to discontinue production of its engine and instead used a Chrysler 313-cubic-inch (5.1 L) V8 engine. And the AC Cars later started using the 159-cubic-inch (2.6 L) Ford Zephyr engine for its production cars.

In September 1961, Carroll Shelby, an American automotive designer wrote a letter to AC Cars asking them to make him a modified car to accept a V8 engine. AC Cars agreed, provided a suitable engine could be found immediately, as previously the Bristol's engine for their two-seat sports car (AC Ace) was discontinued.
1962 Shelby 289 Cobra 'CSX2001' uses a Ford's 289-cubic-inch (4.7 L) V8 engine. (Picture from: http://bit.ly/3qdjCBi)
To get the V8 engine for his car, Caroll Shelby contacted Chevrolet, one of the American car manufacturers to see if they could provide him with a V8 engine. But unfortunately they said no because they didn't want to increase the number of potential competitors for their Corvette car model.

After that he contacted another American manufacturer Ford (who was basically desperate for a car that could compete with the Chevy Corvette) and just happened to have a new V8 engine that could be used in this venture, namely a new lightweight small-block V8 engine named the Windsor 221-cubic-inch (3.6 L). In short, Ford agreed to give Caroll Shelby two units of their new V8 engine.

In January 1962, the AC Cars mechanics at Thames Ditton, Surrey designed a prototype called AC Ace 2.6 with chassis number CSX2000. AC had done most of the modifications needed to apply the small block V8 engine when they installed the 159-cubic-inch (2.6 L) Ford Zephyr inline 6 engine, including extensive rework of the AC Ace front end bodywork. The only modification of the first Cobra (AC Ace 2.6) front end was the steering box, which had to be moved outside to make spacious room for the Ford's new V8 engine.

And the most important modification is the installation of a stronger rear differential to handle the increased engine power. The Salisbury 4HU unit with deep disc brake for reduced the weight was chosen as a replacement for the old ENV unit. It is the same unit used in the Jaguar E-Type.
After testing and modification, the engine and transmission were removed and the chassis was airlifted to Shelby in Los Angeles on February 2, 1962. At this time the displacement of the small block was increased to 260 cu in (4.3 L). Shelby's team paired this engine along with the transmission into the CSX2000, in less than eight hours at the Dean Moon workshop in Santa Fe Springs, California, and started road testing.

The Production Models (CSX/CS 2001-2602)
Furthermore for the production model (CSX/CS 2001-2602), there were some significant changes made such as the position of the inboard brakes being moved out to reduce costs, then the fuel tank filler was moved from the fender to the trunk center, and the trunk lid had to be shortened to accommodate those changes.
1963 Shelby 289 Cobra Mk II uses a Ford's 289-cubic-inch (4.7 L) V8 engine. (Picture from: https://bit.ly/38Enrtn)
Then the AC Cars exported the finished, painted, and trimmed (minus engine and gearbox) cars to Shelby. After arriving in America, Shelby then finished his cars at his workshop in Los Angeles by installing engines and gearboxes and repairing any bodywork deficiencies caused by the car's shipping by the sea.

A small number of cars were also completed on the East Coast by Ed Hugus in Pennsylvania, including the first production car; CSX2001. Following later the first 75 Cobra Mk1 models (including the prototype) were paired with 260 cu in (4.3 L). And the remaining 51 Mk1 models were paired with a larger version of Ford's Windsor engine, ie the 289-cubic-inch (4.7 L) V8.
1963 Shelby 289 Cobra 'COB6004' uses a Ford's 289-cubic-inch (4.7 L) V8 engine. (Picture from: https://bit.ly/38EO1mg)
In late 1962, Alan Turner, the AC Cars's chief engineer completed a major design change from the car's front-end to accommodate rack and pinion steering while still using transverse leaf spring suspension (with double leaf spring as the top suspension link). The new car entered production in early 1963 and was designated as the Mark II. The steering rack is borrowed from the MGB while the new steering column comes from the VW Beetle. About 528 units of the Mark II Cobra were produced in the summer of 1965 (the last US-made Mark II was produced in November 1964).

The European Models (COB/COX 6001-6062)
As for the Cobra's European models, (COB/COX 6001-6062) carried out since 1963 after the Ruddspeed Ace production was discontinued, it was done to keep the company's production activities focused on the Shelby American Inc. car production. And the AC Cars took the  marketing and selling portions of the Cobra models for the European's market with the advertisement's statement that Cobra is designed to meet Shelby American Inc.'s requirements.
1964 Shelby Cobra 427 'CSX2196' or Fliptop Cobra uses a 390 cu in (6.4 L) Ford FE engine. (Picture from: https://bit.ly/38Enrtn)
Besides that, there was also a 390 Big Block Cobra, which was originally done to facilitate the Shelby's experiments with a 390 cu in (6.4 L) Ford FE engine on the car with chassis number CSX2196 was intended to overpass the Ferrari's models in the GT class. Unfortunately, The car development failed and was discontinued.

It was decided after Ken Miles drove and raced the FE-powered Mark II at the 12 Hours of Sebring and said the car almost unsavable, and named it the Turd. It failed to touch the finish line and must stop in early due to engine (damper failure) problem.
1967 Shelby Cobra 427 S/C Roadster uses a Ford's 289-cubic-inch (4.7 L) V8 engine. (Picture from: http://bit.ly/35D4zcb)
Subsequently CSX2196 was revised and prepared for the fight in Nassau which allowed for a more relaxed class division. It allowed the Cobra GT to run on the prototype Ford GT, GM Grand Sport Corvettes, and Lola Mk6. And for the 1964 event, the Fliptop Cobra was used with a 390-cubic-inch (6.4 L) aluminum engine. That's very fast and at the end of the first lap, it has the long straight start-finish advantages. However, at the end the car failed to finish due to the brake problems.

Unique Facts of the Shelby Cobra Daytona Coupe CSX2286
There is a unique fact regarding the Shelby Daytona Coupe. As it is known, Caroll Shelby from the start had a strong ambition to beat Ferrari cars in the world famous 24-Hours of Le Mans racing event. At the time, due to his racing car could not be completed in time and not able to appear at the racetrack, so (reportedly) to save face, then he made up a story that the Peter Brock-designed Shelby Cobra Daytona Coupe with chassis number CSX2286 especially for the 24 Hours of Le Mans in the 1964 was badly damaged after being involved in a road traffic accident while being transported to the racing circuit.
This is one of the six of the famous 1964 Shelby Brock Cobra Daytona Coupe 'CSX2286' while at the 2007 Monterey Historic Automobile Races. (Picture from: https://bit.ly/3sfYtbD)
Even so, Caroll Shelby finally succeeded in completing and fulfilling his dream at the 24 Hours of Le Mans racing event two years later (in 1966) by defeating the Ferrari cars with the legendary Ford Motor Company-owned, the Ford GT-40 racing car. And all of those triumph momments are pictured beautifully in the Hollywood's movie titled 'Ford vs Ferrari' and that can be a reference to find out one version of the story.
Finally, even though it's more than half a century old, the Shelby Daytona Coupe still shows a strong charisma. Even if the other cars price continues to fall from year to year, but not for it, this Cobra still has high value and exorbitant price. And today, the car estimated has the price reaches of Rp. 78.7 billion. Wow! As quoted of Carbuzz, the mentioned car is one of the 6 units of the Peter Brock-designed Shelby Daytona Coupe ever built specifically for the racing events in 1964. *** [EKA | FROM VARIOUS SOURCES | CARBUZZ | MOTORAUTHORITY ]

Vespa Elettra, an elettro design for a classic soul by MA-DE STUDIO

Recently, the trend of electrification in the two-wheeler segment has also begun to develop rapidly, marked by an unprecedented boom in popularity, especially in recent years. Various well-known motorcycle manufacturers have started to introduce and even sell electricity-based products.
Vespa Elettra, elettro design for a classic soul by MA-DE STUDIO. (Picture from: http://bit.ly/2ML6WmD)
But the sophistication of an electric motorbike has not been able to shake the tastes of classic motorcycle lovers who remain faithful in choosing conventional classic motorbikes, and this also includes classic Vespa scooter fans who can be said to be one of the largest fan communities in the world.
Vespa Elettra, elettro design for a classic soul by MA-DE STUDIO. (Picture from: http://bit.ly/2ML6WmD)
As we all know, Vespa is the most iconic Italian scooter brand in the world. But to be more specific, we are talking about the Piaggio's Vespa model which was patented almost 75 years ago, to be precise April 1946. Until now, Vespa scooters have had a fantastic total sales figure, reaching 18 million units worldwide. So it is not surprising that Vespa has many loyal fans around the world
.

In the context of the electrification trend of motorized vehicles, it has also begun to touch the scooter sector, particularly Vespa scooters. Piaggio, as the manufacturer that holds the Vespa brand, has also tried to follow this trend. There are several models of electric scooters that this manufacturer has tried, namely the Vespa Elettrica which was introduced to the public for the first time in 2016.

However, the foregoing does not reduce the interest of third parties outside the Italian giant scooter maker to try to come up with creative ideas in the form of electric vehicles which are design inspired by the Piaggio's classic scooter.

Here's MA-DE STUDIO is answered the above questions in their latest project. "This project is not an official Vespa assignment, but something we created because of our love for this iconic Italian Vespa brand," said Andrea Della Vecchia, founder of MA-DE Studio Design, as quoted of Autoevolution.

MA-DE Design Studio itself is an international design studio based in Cuomo, Italy, so it makes perfect sense that they involve Vespa models in this serious project. As a form of support for the scooter, the pride of the Italian state.
Vespa Elettra, elettro design for a classic soul by MA-DE STUDIO. (Picture from: http://bit.ly/2ML6WmD)
The electric-powered scooter named Vespa Elettra, to be elettro design for a classic soul, is designed very attractive and inspired by the classic Vespa scooter, which is also known as the Vespa which is transformed into an electric scooter without losing its classic identities and souls. 

Everything looks harmonious together, starting from the classic handlebar on which there's a sophisticated dashboard and equipped with a touch screen with high technology. Then as the drivetrain, the scooter uses an electric motors that is capable of producing 9.38 horsepower with 240 Nm of torque, so that it can make it go at a maximum speed of up to 95 kph.
It armed with a 5.6 kWh battery, so the electric-powered Vespa Elettra scooter can cover a distance of 150 km for a single battery charge, far above the word that is enough to be used everyday around the city with this eccentric-style scooter.

But what is also no less cool than this 'classic' with the latest technology is the Bluetooth connectivity feature to be paired with a special application, which becomes an authentication key and a virtual dashboard for relevant travel settings and data.

“I really believe in the movement towards electric mobility. It's only a matter of time, not only for cars but also for scooters and other small vehicles as mobility vehicles in urban areas,” concluded Della Vecchia.

In fact, this is not the first time a third party has come up with a creative idea in the form of an electric-powered scooter concept inspired by classic Vespa scooters, such as the Vespampère electric scooter concept by Giulio Iacchetti, the Vespa 98e Concept by Mightyseed Designs, which was present some time ago.

And here's the soundless Piaggio Vespa Elettrica video, while passing through your heart.😀
Kept spur your adrenaline on the power of the two-wheeled monster and stay alive with true safety riding. May God will forgive Your sins and so does the cops...... *** [EKA | FROM VARIOUS SOURCES | VESPA | MA-DE STUDIO | EICMA 2019 | AUTOEVOLUTION | ELECTRICMOTORCYCLES ]

Rare Corvette Corvair Fastback

While we were surfing in cyberspace, for a moment we were amazed at a beautiful classic car called the Chevrolet Corvette Corvair Concept released in 1954. Uniquely, even though it carries the big name of Corvette, it has something unique appearing on the back that makes it more similar to the Ferrari 250 GT SWB 'Breadvan' Drogo.
1954 Chevrolet Corvette Corvair Concept combines two separable items, in this case the Corvette and the Bell Air, which its debut at the 1954 Motorama in New York. (Picture from: http://bit.ly/38wkeMo)
It's exciting that the Corvette also has a fastback variant, even though it's only a concept car. After doing some searching on the internet to resolve the curiosity of this car, we finally got quite valid information about it from several sources. Yes, this car appeared long before there was the Corvair of the 1960s
. 
1954 Chevrolet Corvette Corvair Concept's top is said to be inspired by an airplane, which sweeps backwards and tapers gracefully into the rear design. (Picture from: http://bit.ly/38wkeMo)
As quoted of the Rare Car Network website, the Corvette Corvair is a very creative concept, a flowing fastback style exercise, which made its debut at the 1954 Motorama in New York. The name portmanteau combines two separable items, in this case the Corvette and the Bell Air.

According to the GM Heritage Center, the production version of the model was then stalled and abandoned, due to slow sales figures for the Corvette at the time (1954). And usually concept cars that had expired in that era would be destroyed, but this Corvette Corvair fastback coupe reportedly survived the crusher, but strangely there was no trace of it.
1954 Chevrolet Corvette Corvair Concept seats appear to have a fiberglass-made divider between them, in a similar way to the Corvette roadster. (Picture from: http://bit.ly/38wkeMo)
There is also news that more than one car was actually built, but no document appears as verification. Until now, it is not certain how many units of the Corvette Corsair concept car was made by the American car manufacturer.

Apart from these two stories, there are a number of sources who say that the original 1954 Corvette Corvair concept was destroyed in that period, and then an authentic restoration project was carried out using the original 1954 Chevy Corvette chassis.
1954 Chevrolet Corvette Corvair Concept uses a 235.5 cubic-inch six-cylinder engine that offers 150 horsepower accompanied by a 2-speed Powerglide transmission system. (Picture from: http://bit.ly/38wkeMo)
It is necessary to determine which one is correct among all the information above, but what is certain is as quoted from the Rare Car Network that the cars that exist today (at least those discussed by him) are only limited to replicas. And the Corvair name, however, came to be used in the 1960 Corvair rear-engined compact car.

The beautiful appearance of this two-door fastback is exuded, as it has the front end of the Corvette, the enveloping windshield and design details on the rear that resemble a jet-fighter exhaust port. While the cut tail seems to be influenced or inspired by European designs (maybe the Ferrari 250 Breadvan Drogo).

Furthermore, the top is said to be inspired by an airplane, which sweeps backwards and tapers gracefully into the rear design. Apart from that the roof also provides a glimpse of the quarter windows and C-pillar treatments of the 1958 Corvette.

The car, which is built on the original chassis of the Corvette, has a 102-inch wheelbase and uses a 235.5 cubic-inch six-cylinder engine that offers 150 horsepower accompanied by a 2-speed Powerglide transmission system to distribute power to drive its rear wheels. 
On the interior, the seats appear to have a fiberglass-made divider between them, in a similar way to the Corvette roadster. Much of the interior is largely stock, and the roof appears to have been grafted directly onto a production Corvette. No storage behind the seats. Even though it has a fastback design, it doesn't change the interior layout of the Corvair Concept. 
After not being seen in public for a long time, it was discovered that one of the beautiful cars (sea foam green color) was seen on the back of a trailer at the Bloomington Gold Corvette show in St. Charles, Illinois in 2011 (you can see on the Manonthemove website). And the last one of the replica cars (in red) also appears to be on display in a collection of the National Corvette Museum in Bowling Green, Kentucky. *** [EKA | FROM VARIOUS SOURCES | MANONTHEMOVE | RCNMAG | CONCEPTCARZ ]

Jaguar Vision Gran Turismo SV for Gran Turismo 7

As in the Gran Turismo 6 virtual racing game previously it is known that many world manufacturers have released the VGT (Vision Gran Turismo) concept. It seems that Polyphony Digital, the game developer wants to try again when Gran Turismo 7 is available to play on the PlayStation 5 (PS5) console.
The latest Jaguar Vision Gran Turismo SV concept car can be driven virtually in the Gran Turismo 7 racing game on the Sony Play Station 5 (PS5). (Picture from: https://bit.ly/38wPr27)
Reportedly, the latest sequel to the virtual racing video game Gran Turismo 7 will be released this year (2021). And ahead of its launch, the world-renowned automotive manufacturers began making concept cars that could later be driven virtually in the aforementioned racing game.

And the company that was the first to officially release its concept for the Gran Turismo 7 was Jaguar through its newest concept car called Jaguar Vision Gran Turismo SV. For the latest version, Jaguar takes a design approach towards an endurance prototype racing car. Previously, Jaguar had also released a similar concept in 2019, called the Jaguar Vision Gran Turismo Coupe.
The latest Jaguar Vision Gran Turismo SV concept car (in the middle) posed with the old Jaguar racing car models such (from left to right) Jaguar C-Type, XJR-9, XJR-14 and D-Type. (Picture from: https://bit.ly/38wPr27)
In theory, because this car is a virtually concept, the Jaguar Vision Gran Turismo SV can be described briefly as an electric-powered racing car that relies on four electric motors, with a total power output of 1,877 hp and 3,360 Nm of torque. With such a large number of Power and torque, then the British company claims its latest car has the ability to accelerate from rest to 100 kph in 1.65 seconds. While the top speed it will touch is 410 kph.
The latest Jaguar Vision Gran Turismo SV concept car appeared in a very streamlined design applied to the car, through a long bonnet line coupled with a low roofline, which is almost in line with the height of the front fenders. (Picture from: http://bit.ly/3oyZuJv)
Of the visual appearance, you will see a very streamlined design applied to the car, through a long bonnet line coupled with a low roofline, which is almost in line with the height of the front fenders. Then the front fascia shows a closed grille to house the Jaguar emblem, because it has an electric drive. Then under it is attached a long and width splitter, which is cut off in the middle.
The driver of the latest Jaguar Vision Gran Turismo SV concept car is in an ergonomic position when driving the car with all the instruments positioned so that they are easily accessible to the driver's hand. (Picture from: http://bit.ly/3oyZuJv)
Meanwhile, on the sides there are almost no air holes, except for one vent which has the function of removing air pressure from behind the front fenders. The rest there is no ventilation or intake at all on the side of the Jaguar Vision Gran Turismo SV. The British premium car manufacturer also mentioned several design references applied to this concept taken from old Jaguar models such as the C-type, D-type, XJR-9, and XJR-14. Moreover, the giant rear wing also reminds us of the Jaguar racing car that once competed in the 24-Hours of Le Mans.

In dimensions when compared to the Jaguar VGT Coupe, the Jaguar Vision Gran Turismo SV is 861 mm longer. All parts of the body are utilized to generate maximum downforce, including the fully closed bottom. Not only closed, but also given special sculptures for the best air flow to the diffuser. As a result, the car's drag coefficient (Cd) is only 0.398, with 483 kg of downforce generated when the car's speed reaches 322 kph.

The interior is also made in such a way as to support aerodynamic performance, so when in the cockpit, so the driver is in an ergonomic position when driving the car with all the instruments positioned so that they are easily accessible to the driver's hand. All control devices are also designed to keep the car's weight light by using Typefibre material. These materials are used to make composite seats, which reportedly will also be tested on the Jaguar I-Type is will be used as the Formula E racing cars next season. 
"The Vision GT SV is a dramatic and visually captivating car, showcasing what is possible when the traditional boundaries that govern real-world car design are completely removed. In bringing this car to life with a full-size design study, we were able to showcase the most extreme version of the Jaguar electric racing car that is inspired by the past, but looks fearless into the future," said the Jaguar's director of design, Julia Thomson.

"All aerodynamic features have been painstakingly optimized through cutting-edge computational fluid dynamics analysis - in exactly the same way we do real-world projects like the Jaguar I-TYPE Formula E race car," said Jaguar SV senior aerodynamic engineer Michael O'Regan. *** [EKA | FROM VARIOUS SOURCES | JAGUAR | AUTOWISE | ]

Zora Duntov's Corvette SS race car concept of 1957

The beauty of the design, the powerful engine and the compact dimensions were the reasons of many people fall in love with the Corvette legendary roadster made by Chevrolet. Might be this was what the auto engineers and designers at the one of American automotive giant subsidiaries tried to promote when they first launched the legendary model.

This can be seen in the Chevrolet Corvette SS, a gorgeous and powerfull as well concept car that was deliberately made initially with the aim of competing in the 24-Hours of LeMans, but was later touted as the forerunner of many Corvette sports/racing car models.
1957 Chevrolet Corvette SS sat on display at the 17th Annual Amelia Island Concours d'Elegance in 2012. (Picture from: http://bit.ly/3buFGmZ)
The concept car's design and construction process was carried out by the GM's  team of engineers and designers led by the talented Zora Arkus-Duntov, to create a lightweight and powerful racing car and took the Mercedes 300SL as their based template.

Before we discuss more about the car, it's good for us to get to know a little about Zora Arkus-Duntov. He is a Belgian-born American engineer whose work at the Chevrolet Corvette earned him the nickname "Father of the Corvette."
The talented engineer Zora Arkus-Duntov sat behind the wheel of his creation 1957 Chevrolet Corvette SS. (Picture from: https://bit.ly/2XEcAJL)
As a result, the car was lightweight thanks to using the magnesium made bodywork (with only a weight of 1,850 lbs) enveloping the tubular steel frames, it also features with the front suspension of coil-over-shocks, de Dion rear axle and built-in aluminum drum brakes.

The Duntov's team only made two chassis, the first was a test car dubbed the 'Mule' and the other to be a race one. Then as their drivetrain, it's pinned under the hood a small block V8 engine with fuel injection which can produce power reaching of 307 horsepower at 6,400 rpm.

After the cars completed in 1957, the first test would not be carried out at the 24-Hours LeMans, but in an almost similar race but shorter in America, namely the 12-Hours of Sebring. Although the racing results of the Corvette SS for the first time at Sebring were not going well, where suspension problems and another mechanical failure forced it stop after speedy only in 23 laps.

However, the Chevrolet Corvette 'SS' managed to set a new lap record in that race. So General Motors is very enthusiastic about the potential of the SS based on those results of the training and the speed of the laps.

Not only that it turned out, Juan Manuel Fangio, the winner at the 12-Hours Sebring of 1957, was quite impressed with the car, and then tested the Corvette SS in training sessions. The results were astonishing, Fangio completed his one full lap of 3: 27.4 seconds, that's faster in a car he had never driven before than any other driver could in a car they had driven before.

Despite GM's enthusiasm, unfortunately the Corvette should be scrapped several months later, as the American auto-making community band together to ban the manufacture of factory-produced racing cars. This was triggered by a great accident that occurred at the 24-Hours Le Mans of 1955 which claimed the lives of 83 people, since then the public attitude towards automotive racing has changed drastically.

Protests forced many companies to withdraw from racing, organizers reviewed safety rules, and Mercedes, which was accused to involve directly to the accidents mentioned above then decided to refuse to participate in any auto races until the 1970s.
But it won't stop GM from launching the Corvette as a sports car for the layman who likes to combine the look and feel of a race car with the comfort of a daily-using vehicle. Then Zora Arkus-Duntov, those car's engineer-designer, presented it to the Indianapolis Motor Speedway on May 29, 1967, during the drivers meeting before the 51st Indy 500 mile race started, paced by the Chevrolet Camaro.

And then it's no surprise that to this day, the Corvette is renowned for producing some of the finest cars not only in the United States, but all over the world... *** [EKA | FROM VARIOUS SOURCES | HEMMINGS | CONCEPTCARZ | WIKIPEDIA | RCNMAG | CORVETTEBLOGGER ]
